Descrição
NGC 4559 is a barred spiral galaxy in Coma Berenices, about 29 million light-years away. It is a loose, patchy spiral with numerous HII star-forming regions and appears roughly 10 arcminutes long with low surface brightness.
Dicas de Observação
Visible as a faint, elongated glow in a 6-inch telescope. Dark skies are important for this low-surface-brightness galaxy. Best viewed in spring evenings at low to medium magnification.
História
Discovered by William Herschel on April 11, 1785. X-ray observations have revealed an ultraluminous X-ray source in this galaxy that may be an intermediate-mass black hole.
Curiosidades
NGC 4559 contains an unusually large number of bright HII regions for its size, indicating vigorous ongoing star formation.
